Which boxer was nicknamed 'Marvelous'?

Which boxer was nicknamed “Marvelous”? Marvin Hagler was nicknamed “Marvelous Marvin Hagler.”

Hagler was one of boxing’s defining middleweights, reigning as the undisputed world champion from 1980 to 1987. He made 12 successful defenses of the undisputed middleweight championship and finished his career with 62 wins, including 52 by knockout, in 67 professional bouts.

The nickname became official in an unusual way. Hagler was frustrated when announcers sometimes omitted “Marvelous,” so in 1982 he legally changed his name from Marvin Nathaniel Hagler to Marvelous Marvin Hagler. He was born in Newark, New Jersey, and later became closely associated with Brockton, Massachusetts.

Hagler is often grouped with Sugar Ray Leonard, Thomas Hearns, and Roberto Durán as one of boxing’s “Four Kings.” His 1985 fight with Hearns, followed by his 1987 bout with Leonard, helped define a celebrated era of modern boxing.
